Hi Cd_Sharp, Very Nice!
I think that the Currents in the Coils, the Magnetic Fields, are not opposing maybe? Can you check with a Scope?
I have a small Measurement Block I use, similar to the last ones I showed prior, but this is only to measure Currents:
With these, I can monitor the Currents in the Coils all the time. I can fiddle to get the best result. Maximum Current Amplitudes are about where the best results are obtained.
The Metal Strip Through Home Resistors are 0.1 Ohms (0R1) and are pretty good for this sort of thing. Very low Circuit impedance, but still sufficient to make a reasonable good measurement.
Recently, I did some experiments, where I had trouble getting the Currents to oppose, something very odd going on, I will show more on this soon. Electromagnetic Induction is Equal and Opposite, this is Lenz's Law, it is built into Electromagnetic Induction and will never change, so I need to try to explain why sometimes we don't get this Opposition!
Re Symmetrical Coils:
Yes, you can have Symmetrical Coils and because the Magnetic Field is NI/L the Field is Symmetrical with the Same number of Turns (N) and Current (I)!
But, please remember, if there is a situation where you use Symmetrical Coils, equal turns on each Coil, then there is always an offset of approximately 1/4 to the turns on the Primary, or Input Coil. Don Smith shows this very Clearly:
- L1 = 4 Turns
- L2 = 16 Turns
- L3 = 16 Turns
Don regularly terms the Output Coils, Partnered Output Coils as a single Coil, normally only using the L2 label. I have found it best to deem this Coil in Two Parts, because each part of the Coil has two different functions.
I hope this helps
